Males of the parasitic wasp genus Nasonia use blends of chiral hydroxylactones as sex pheromones to attract conspecific females. Whereas all Nasonia species use a mixture of (4R,5S)-5-hydroxy-4-decanolide (RS) and 4-methylquinazoline (MQ) as sex pheromones, Nasonia vitripennis evolved (4R, 5R)-5-hydroxy-4-decanolide (RR) as an extra sex pheromone component. We recently identified and functionally ...
